Abstract: This disclosure relates to techniques for modifying connected mode discontinuous reception (C-DRX) cycle length based on mobility and signal conditions. According to some embodiments, a wireless device may establish a radio resource control connection with a base station providing a cell of a cellular network. A C-DRX configuration may be established with the base station, including selecting a C-DRX cycle length. One or more conditions configured to trigger the wireless device to request C-DRX reconfiguration may be detected. The one or more conditions may be based on mobility and/or signal conditions of the wireless device. A request for C-DRX reconfiguration to the base station may be transmitted based on detecting the one or more conditions. C-DRX with the base station may be re-configured based on the request for C-DRX reconfiguration.

Abstract: A network reselection procedure, of a wireless communication device, that occurs following a network detachment event, such as a device sleep event or a device power savings mode event. The wireless communication device attempts to acquire a first wireless network to which the wireless communication device was most recently attached, immediately preceding the network detachment event. Then, in response to an unsuccessful acquisition of the first wireless network, the wireless communication device attempts an alternate network acquisition utilizing a Most Recently Used List (MRUL) that is stored at the wireless communication device and includes information about one or more frequency bands allocated to a primary service provider with which the wireless communication device is affiliated. After determining whether the alternate network acquisition attempt was successful, the wireless communication device attaches to a second network and stores information associated with the second network.
